Title: Improvements in master cylinders for liquid pressure power transmission systems
IPC: B60T11/20
Filed: 1938-03-12
Abstract: 508,889. Hydraulic transmission of power; brakes. AUTOMOTIVE PRODUCTS CO., Ltd., and GATES, G. R. G. March 12, 1938, No. 7788. [Class 69 (ii)] [Also in Group XXXIV] In master cylinder units for operating vehicle brakes &c., of the kind comprising two or more pressure spaces each connected to one or more slave cylinders, the pressure spaces being mutually isolated by a floatpiston, the unit comprises main and auxiliary cylinder bores disposed side by side, there being a floating piston in the or each auxiliary bores. In the event of failure of the fluidpressure in a space one piston may operate another mechanically. A casting 1 has main and auxiliary bores 2, 3 containing respectively, a pedal operated piston 18 and a floating piston 28. A cover 12 bolted to the casting provides a space 13 connecting the bores. The outlet 4 from the bore 3 may be connected to the front brakes of a vehicle and a connection 16 at the upper part of the cover 12 may connect the space 13 to the rear brakes. If, when the piston 18 is moved to operate the brakes, the fluid pressure in the main bore and the rear brake system fails, a projection 38 on this piston engages a rocker 35 pivoted in the space 13 to operate the piston 28 and the front brakes and if the pressure in the bore 3 and the front brake system fails, the piston 28 engages an abutment 55 thus ensuring application of the rear brakes. The casing 1 comprises separate upper reservoirs 6, 7 which are connected by apertures to the spaces 24, 32 around the pistons and by other apertures normally to the cylinder spaces in front of the pistons, these other apertures being covered by the pistons upon the initial movement thereof. Two-way valves adapted to retain a slight pressure normally in the pipe lines are arranged at the outlets 4, 16 and comprise each a metal cup urged by a spring 51 against a packing ring 52 and a rubber cup 46 within the metal cup. Liquid can pass freely out of the cylinder through holes in the metal cup, past the skirt of the rubber cup but can only return by lifting the metal cup against the spring. A second auxiliary bore may be arranged at the other side of the main bore 2, a rocker being provided for emergency operation of each floating piston or further auxiliary bores may be added in series so that the pressure created by one floating piston operates another.

Title: Improvements in electrical information storage devices
IPC: G11C13/00
Filed: 1955-03-18
Abstract: 764,745. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 18, 1955 [March 23, 1954], No. 7919/55. Class 106 (1). ). An electrical storage device comprises a plurality of coherers for storing data, read-in circuits responsive to data received for storage for cohering coherers corresponding thereto, and read-out circuits responsive to the conditions of the coherers for examining the condition of the coherers and for effecting read-out of information stored therein. Each coherer, e.g. 52, Fig. 1a, is such that when a sufficiently high voltage is applied across it it " coheres " and its resistance drops from a relatively high value to a low value. The coherer remains in this state even though the power supplies be removed, until it is physically shaken when it is " decohered " and returns to its normal high resistance. The storage device described stores three decimal digits. Each digit, with the exception of zero, is stored on a " one " " two " " four " " eight " code by the upper four groups of three coherers-the three coherers in each group corresponding to the three digits-and zero is stored positively by the lowest group of three coherers. Access to the coherers is via a six-bank stepping switch having banks a-f and contacts 42-15. As described, contacts 45 a-f are not used but each of the other three sets of contacts 42 b-f 43 b-f, 44 b-f, corresponds to one digit position of the store. Data entry is by a ten-key keyboard. Each key, when depressed, energizes an associated relay which causes - 250 volts to be applied to those groups of coherers representative of the value of the key depressed, the particular coherers that are cohered depending upon the position of the stepping switch, which is shown in the position corresponding to the first digit position. Depression of a key also causes, by means not shown, a contact 49 to be closed resulting in the energization of a magnet 48 upon the de-energization of which the stepping switch advances one stage. A key 21 causes the stepping switch to advance one stage without entering any data, and a key 22 energizes a decohering solenoid and causes the stepping switch to return to a reference position. Read-out is effected by five hard valves controlled by leads 68-71 each having a relay coil as its anode load. The contacts of the read-out relays are so arranged that only one of ten output leads representative of a stored digit is energized, and means are provided (two hard valves and two relays) which, as soon as an output lead has been energized causes it to be de-energized and causes the stepping switch to advance one stage to read-out the next digit. Thus once read-out is commenced the device automatically reads out the complete number serially digit-by-digit on ten parallel leads.

Title: Improvements in or relating to machines for wrapping articles of a uniform or approximately uniform size and shape
IPC: B65B25/18
Filed: 1925-01-31
Abstract: 251,312. Mellor, L. Jan. 31, 1925. Packeting by wrapping-up.-Relates to machines for wrapping loaves, cakes, &c., and of the type in which the loaf &c. is deposited on a wrapper lying on a tray or table, the wrapper is partially folded around the article while on the tray and the completion of the folding and the sealing are effected as the article is moved away from the table. According to the invention, the folding is commenced by the wrapper being carried round the article by an arm or folder encircling or partly encircling the tray or table. As shown, a sheet of waxed paper is laid on a table 13 and a loaf placed upon it. A lever 29 is then turned over to the right and operates an arm 14 through a link 27, crank 26, pawl 26<a> and ratchet 24. The ratchet 24 is fast to a toothed wheel 21 which drives a wheel 17 to rotate the arm 14, on which a folder 15 is adjustably mounted, so as to carry the wrapper over the top of the article and to leave the free end hanging down in front of the table 13. Meanwhile, end folders 33, comprising right-angled members adjustably pivoted opposite each other, on the lever 29 have made the first and fold. and the continued advance of the article carries it past folders 59 which make the second end folds, leaving triangular tabs at the top and bottom of the ends. The free end has previously been folded up by a plate 57. The ends folded down and up respectively by slots in a plate 58, and the package, moved to the right by succeeding packages, arrives between heating elements 69, which seal the ends, and into a cooling trough 67. In a modification, Figs. 4 and 5, the plate 58 is replaced bv a plate 72, edges 68, 69 of which turn both end tabs downwards through a gap between the base-plate 71 and the sides. Edges 73, 74 fold up the tabs against the base of the article. All the folding elements and the sides of the sealing and cooling troughs are resiliently and adjustably mounted. Parallel supports 41, Fig. 1, carry longitudinally adjustable brackets 43 from which the parts 58, 66, 67 are adjustable by means of right- and left-hand screws. When ordinary paper is used, the folds may be secured by adhesives.

Abstract: 371,127. Control of motors. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London, MACKLEY, A. H., 15, Waterloo Road, Bedford, and TAYLOR, J. R., Monterey, Uddingston, Glasgow. March 17, 1931, No. 8155. [Class 38 (iii).] Travelling between predetermined limits.-A feed motor 1 of a slotting or planing machine is started every time a tappet switch 19 is momentarily closed on to contact 21 at the end of each stroke of the machine, and runs for a distance predetermined by the position of a switch 9. Closure on to contacts 21 causes energization of a relay 5 over a stepped drum 7. The relay maintains itself over the drum and causes - closure of contactor 3. The motor 1 drives a shaft 11 and rotates the drum 7 until the circuit of the relay 5 is broken. Whereupon contactor 3 opens and at auxiliary contacts 23 completes a circuit, prepared at contact 20 by return of tappet switch 19 and at contacts 24, 25 closed by a cam 26 as soon as the drum 7 has moved from its initial position, for a coil 18 which frees a band 17 and allows the drum 7 to return to its initial position under the action of a spring 27. A button 28 in parallel with the contacts 19, 21 gives a repeat operation of the motor independently of the tappet switch, and a " continuous " button 29 gives a continuous operation of the motor with the coil 18 energized so that the drum 7 is not displaced. In a modification the direction of rotation of the motor can be preselected.

Abstract: 1,082,811. Magnetic amplifiers. C. A. PARSONS & CO. Ltd. Feb. 25, 1965 [Feb. 27, 1964], No. 8235/64. Heading H3B. The static voltage gain of a resetting magnetic amplifier is made linear by introducing feedback from a winding on the saturable magnetic core to the control circuit. In a push-pull circuit having two saturable cores 9, 10 with reset windings 7, 8, a control signal is applied to input transformer 21 to control the biasing of a transistor 12. In the absence of an input signal the transistor is biased near " bottoming," so that when an input signal is applied the bias is reduced during alternate half-cycles and one core 9 or 10 is only partially reset. A load 22, 23 is connected through thyristors 24, 25 to secondary winding 4 of mains transformer 1. While a core is being set by current in winding 26 or 27 insufficient voltage drop exists across resistors 30, 31 to trigger the associated thyristor, and no load current flows. When core 9 or 10 is saturated the associated thyristor is triggered. Each core 9, 10 has a linearizing feedback winding 19, 20 in series with the base of transistor 12, which injects feedback by transformer action during the part of a half-cycle when a core is reaching saturation. Depending on the phase sense of the control signal relative to the mains supply one or other thyristor conducts for a portion of a half-cycle while the other remains non-conductive. In the positional control system shown, the current in load coil 22 or 23 moves armature 45 one way or the other. Position and velocity feedback are also provided from transducers 46, 48 to transformers 47, 49.

Title: Improvements in or relating to devices for the protection of equipment connected to an electric low-voltage network, in particular to a telephone network
IPC: H01T1/14
Filed: 1955-03-23
Abstract: 765,050. Protective cut-out arrangements. DEMAN, A. March 23, 1955 [March 23, 1954], No. 8435/55. Class 38(5) In an arrangement for protecting equipment 2 connected to a low voltage network 1, e.g. a telephone network, from overvoltages, an overvoltage arrester 3 is combined with a thermal switch operative to isolate the equipment 2 and short circuit the arrester 3. The switch may comprise a stressed contact spring 4 mounted on the upper terminal 7 of the arrester and normally secured to a collar 6 by a fusible element 5, and a contact member 8 fixed to the lower terminal 9. Overvoltages of short duration are discharged through the arrester 3 without any further action occurring, but should an overvoltage persist, the heating of the arrester causes the melting of the element 5 to enable the spring 4 to move away from the collar 6 to interrupt the circuit to the equipment 2 and to engage the member 8 to short circuit the arrester. Flashover from the spring 4 to the collar 6 may be prevented by an insulating member which is moved by a spring along the contact spring 4 as it moves away from the collar (Fig. 3, not shown). In an alternative arrangement the spring 4 is a bimetallic member which normally abuts the collar 6. The combination, or a number of them, may be enclosed in a box having a lid which when opened opens contacts in the earth connection to cause the lighting of warning glow lamps if the overvoltage persists (Fig. 4, not shown).
